This article explains how to configure a WS TLS node and why it might not connect after import. It covers entering settings in the client, testing the connection, troubleshooting, and the roles of IP addresses, DNS, and the browser environment. It applies to V2Ray, VLESS, and other nodes that support WebSocket and TLS; refer to the node provider’s instructions for the exact field values.
1. Understand WS, TLS, and the node fields
WS refers to WebSocket transport, while TLS encrypts the connection. Neither is a standalone node protocol. First select a protocol such as VLESS or VMess, then configure WS transport and enable TLS. The protocol, server address, port, and user credentials must all come from the same set of node details; do not mix fields from different nodes.
You’ll typically need the server address, port, UUID, WS path, Host, and TLS server name (SNI). Host is used in the WebSocket request, while SNI is used during the TLS handshake. They may be the same or different. Even if the server address is an IP address, that does not mean you should enter it as the Host and SNI.
2. Import first, then check the key settings
- Install a compatible version from the client’s official distribution channel, such as v2rayN for Windows or v2rayNG for Android. Grant the requested permissions on first launch, and avoid enabling complex routing rules for now.
- Copy the complete node share link and use “Import from Clipboard.” If you have a subscription URL, add it as a subscription and update it. Do not enter a subscription URL as the server address.
- Open the node editor and verify the protocol, address, port, and UUID. Set the transport type to ws or WebSocket and enable TLS in the security settings.
- Enter the path provided by the provider exactly as given, including the leading slash and any parameters. Enter the supplied value in the Host field and the TLS server name in the SNI field. Do not guess fields that the provider has not specified.
- Save and select the node, enable the system proxy or the client’s VPN mode, run a connection test, then visit a commonly used website to verify.
Do not disable certificate verification to get around an error. The port is not necessarily 443; use the value in the node details. If the client reports unsupported parameters after import, update the client or ask the provider for a compatible format instead of deleting fields you don’t recognize.
3. If the connection fails, troubleshoot IP, DNS, and the browser in turn
Check the client logs before changing settings. If the connection times out, first verify your local network and the server address and port, then try another network for comparison. A timeout alone does not prove that DNS is the problem. If you see a certificate mismatch or TLS handshake error, check the SNI, your system clock, and whether the node details have expired.
DNS resolves domain names to IP addresses. If the logs show a domain resolution failure, first confirm that your local network can resolve domains normally, then check the client’s DNS settings. Avoid running multiple proxy tools at the same time. Do not replace the node’s domain with an IP address you found elsewhere; this can cause problems when the address changes and does not replace the need for the correct Host and SNI.
The browser environment usually does not determine whether the node can connect. If the client test succeeds but webpages won’t load, check whether the system proxy is active, whether a browser proxy extension is interfering, and whether Secure DNS is incompatible with your current proxy mode. Temporarily disable extensions or try a clean browser window for comparison, changing only one setting at a time.
4. What to do if it still doesn’t work
Update the subscription and confirm that the node is still active; free nodes may also go offline temporarily. When asking for help, provide the client version, error message, and screenshots with sensitive details redacted. Do not share your UUID, complete share link, or subscription URL publicly. Troubleshooting in the order of “node fields—network—DNS—browser” makes it easier to identify the problem than repeatedly changing every setting.
